Accreditation in analytical laboratories: a critical assessment of its impact on human beings and techniques

Abstract

The relationships between Quality, Quality Assurance and Third Party Approval by accreditation based on formal application of EN 29002, EN 45001 and ISO Guide 25 are briefly outlined for analytical chemical laboratories working in the non-regulated area. The roles of human beings in laboratories and accreditation bodies are discussed and recommendations are made on how to minimize friction during accreditation processes. The structures of the European Accreditation Systems are reviewed and the efforts towards mutual recognition of the national accreditation bodies are described and critically assessed. The lack of competition based on free market conditions in the framework of company law is deplored. The assessment of laboratory systems, rather than assessing the activity of laboratories against technical standards, is recommended (unless it is otherwise requested). The beneficial effects of the process of accreditation on competence and quality of the activity of the laboratory are emphasized.
